ISLAMABAD: Pakistani authorities have initiated steps to obtain travel documents for members of a judicial commission that is expected to visit India for a second time by the end of this month to interview four officials as part of the probe into the 2008 Mumbai attacks.

The Federal Investigation Agency yesterday filed an application in an anti-terrorism court that asked the members of the commission to deposit all necessary documents and passports.

The court of Judge Chaudhry Habib-ur-Rehman is conducting the trial of seven suspects charged with involvement in the Mumbai incident. The judge issued notices to all members of the commission, including defence and prosecution lawyers, to deposit the documents by February 9.

Sources said the commission is expected to visit Mumbai by the end of February.

The panel will cross-examine four key Indian witnesses - the police officer who led the probe into the Mumbai attacks, the magistrate who recorded the confession of Ajmal Kasab, the lone surviving attacker, and two doctors who performed the autopsies of the attackers.

Kasab was hanged last year in a jail in Pune. This will be the commission's second visit to Mumbai.
